Virginia, Dorothy and Particia Larsen

I am trying to find more information on 3 sisters, Virginia, Dorothy and Patricia Larsen. This is the information I have acquired so far: Parents: Henry William Larsen 1883 - 1958 and Anna M Potherweiler 1886 - ? Virginia R: Born Feb. 3, 1920 in Manchester, North Carolina Dorothy Anne: Born Sep. 19, 1922 in Bexar, Texas Patricia: Born 1929 in the Phillipines All ladies were living in St. Louis from 1930 to 1940. After that I have nothing. No death dates, no marriage records, and basically no clue. Any help would be fantastic.
